Choosing Eye Drops

In this video you'll learn how to pick the right artificial tears for daily comfort.

What artificial tears do

Your eyes already have three tear layers; artificial tears just add a smooth, slippery coating that fills gaps and keeps the surface moist, without affecting how many tears your glands make. Common lubricants include carboxymethylcellulose, hyaluronic acid, and glycerin.

Drops vs gels vs ointments

A thin drop clears instantly and works for mild daytime dryness. A gel is thicker, lasts longer but may blur vision for a minute. An ointment is the thickest, best for bedtime, but it makes vision very blurry. Avoid driving right after applying an ointment.

Preservative limit

If you find yourself reaching for drops more than four times a day, it’s time to switch to preservative-free.

Why preservative-free matters

Preservatives like BAK keep bottles sterile but can irritate the eye with frequent use. Preservative-free options use single-use tubes or special valves, so they’re gentler for sensitive eyes or contact-lens wearers. Some multi-use bottles use vanishing preservatives that break down on the eye.

A preserved drop is fine now and then; for an all-day habit, pick preservative-free. Most people find them fine for occasional use.

Choosing at the pharmacy

Decide if you need daytime relief, night-time comfort, or both. Count how often you’ll use them, more than four a day means preservative-free. And if you wear contacts, look for the label that says safe for lenses. Read the ingredient list; avoid drops promising redness relief.

The one rule

The one rule to remember: if you need more than four drops a day, choose preservative-free to avoid irritation. This simple rule saves money and protects eye health.
